CSHD1200 full hydraulic driving the rotation head unit core drilling rig mounted the crawler is mainly used for diamond bit drilling with wire line hoists. It adopted the foreign advance technology of rotation unit rod holding system and hydraulic system. It is suitable for diamond bit drilling and carbide bit drilling of solid bed. It also can be uses in exploring drilling and base or pile hole drilling and the small water well drilling.
(1) Rotation unit (hydraulic driving rotation head) adopted the foreign technique. It was drive by dual hydraulic motor and changed speeds by the mechanical style. It has the wide range speeds and high torque at the low speed .the max torque is 11000Nm when equipment the different motors. so it can satisfy the different project construction and drilling process.
(2) The rotation unit has the more stiffness spindle, transmission accurately and running steadily more advantages in the deep drilling.
(3) The max spindle speed is 1020rpm with the torque 670Nm, so it is suitable the deep drilling.
(4) The feeding and the lifting system use the single hydraulic cylinder driving the chain. It has the long feeding distance character, easy to the long rock core drilling process.
(5) The hydraulic driving head can move away the drilling hole, accompany with the clamp machine system and the unscrew machine system, so it bring the convenient for the rock core drilling.
(6) Rig has the high lifting speed, it can decrease the auxiliary time and improve the rig’s efficiency.
(7) The V style orbit in the mast can sure the enough rigidity between the top hydraulic head and the mast and give the stability at the high rotation speed.
(8) The main winch adopted the BRADEN winch from the USA, work stability and brake reliability.
(9) The wire line hoists has the max speed 205m/min at empty drum, saved the auxiliary time.
(10) Rig has the clamp machine and the unscrew machine, so it is convenient for unscrew rob and decrease the work intensity.
(11) The rig equips the spindle speedometers and the drilling deep gauge. it is convenient to choice the drilling data.
(12) The rig adopted the back pressure balance system to weight the rod .customer can conveniently get the drilling pressure at the bottom hole and increase the bits life.
(13) The hydraulic system is reliable, the mud pump control by the hydraulic valve. All kind of the handle is concentrate at the control set, so it is convenient to solve the drilling incident.
(14) Mounted the crawler and electronic handle control the rig movement.
